How to check PHP handler in cPanel/WHM ?

PHP handler :
A PHP handler defines the method that Apache uses to communicate back and forth with PHP scripts. A php handler loads the php modules and that determines how the php pages loaded on the server. Different types of available PHP handlers are suPHP, DSO, CGI FastCGI.
On Linux server we can change php handler through WHM > Service Configuration > Configure PHP and suEXEC easily but to list and change the active PHP handler through command line option.
